BALL-BEARING.

To all whom it may comer/i Be it known that I, Cr'ums'rrx Dnminz, asubject of the King of Belgium, and a resident of Antwerp, Belgium, haveinvented certain new and useful Improvements in Ball-Bearings, of whichthe following is a specification.

The application No. 779570 filed July 17, 1913 relates to a lubricatorbox with ball bearings for being used in connection with tramway andrail road vehicles and in which a sleeve, engaged around the axlejournal and carrying the ball bearing rotates on said journal andsmoothly slides on same in theaxial direction in order to remove thenoxious effects resulting from the eccentrically and axially directedstrains which cause twisting of the parts. Suchlubricator boxes may beapplied to shaftings and with this object in view improvements have beenprovided which form the object ofthe present invention.

The improvements consist in that the yielding connection between thesleeveand the axle or shaft is no more obtained by means of a boltsecured on the journal or shaft, and engaging a corresponling slot onthe sleeve, but by one or more helical springs surrounding the shaft,and having one end secured to said shaft while the opposite end engagescorresponding boxes provided at the end of said sleeve, thus forming aresilient connection between sleeve and shaft.

The rotation may bea right side one or a left side one according to theposition of the spring when a single spring is used.

When making use of two springs, both directions of, rotation may beprovided.

The invention is shown in the accompanying drawing, which is an axialsection of a lubricator box mounted on a usual shaft, two springs beingprovided.

On a shaft 1 is mounted a lubricator box 2 provided with a' ball bearingand closed by a lateral cover 3 tightly secured to same. Stuffing boxes4. 5 are provided on said box and cover in order to prevent any leakageof oil.

A sleeve 6 smoothly surrounds the shaft 1 and on the opposed ends ofsaid sleeve 6 are provided helical springs 7. 8, one end of which issecured on the shaft 1 while the Specification of Letters Patent.

Application filed July 17, 1913.

Patented Apr. 21, 1914.

Serial No. 779.571.

opposite free end is bent in the axial direction and engages a boreprovided at the cor responding end of the sleeve and having a largerdiameter than that of the spring so that the free end of the latter mayfreely move within said bore. A resilient connection is thus providedbetween the sleeve 6 and the shaft 1, so that the sleeve is carried withthe rotating shaft and freely slides on the latter in order tocompensate the noxious axial and eccentric strains.

'In order to readily engage the sleeve 6 on the shaft, it islongitudinally /slit so that it may be conveniently slit over theperipherical irregularities of the milled shaft.

On the sleeve 6 is mounted the inner ball race 12 of the balls 13. Oneend of said ring 12 bears against a flange 16 of the sleeve 6 while itis secured to the latter by -means of a nut 11 engaging the threaded endof the sleeve. The outer ball race 14 has a spherical outer peripherymaintained by a correspondingly shaped ring 15 which is firmly securedbetween a flange of a box 2 and an extension of the cover 3.

17 is a lubricating ring.

The spring (or springs) connecting'the sleeve with the shaft cause thesleeve to be yieldingly carried with the shaft, so that any shock isavoided while starting, and they continuously bring the sleeve back inits usual position while the movements of same are very smooth ones.

Having now fully described my said in vention what I claim and desire tosecure by Letters Patent, is: p

1. In an anti-friction bearing, the combination of a box, a shaftmounted in the box,

a sleeve in the box and slidably mounted on the shaft, ball bearingssupported on the sleeve, and springs secured to the shaft and to thesleeve.

2. In an anti-friction bearing, the combination of a box, a shaftmounted in the box,

a sleeve in the box, and slidably mounted on the shaft. one end of saidsleeve having a flange and a notch and the opposite end being threadedand formed with a notchycoil springs mounted on the shaft opposite eachend of the sleeve, one end of each of said springs being secured to theshaft and the opposite end engaging in one of the notches in the sleeve,a ball race member mounted surface in which the convex surface of the onthe sleeve and bearing against the flange, outer ball race fits.
